Manual revolver switching
If a manual action is used to rotate the revolver, this information must be forwarded to the tool management. The
asynchronous transfer function of FC 8 must be used to transfer the modified positions of the revolver. This must
only occur once on the first manual rotation in the sequence. In this case, the following parameterization of the
asynchronous transfer is needed via FC 8:
TaskIdent = 4
TaskIdentNo = channel
NewToolMag = Magazine number of the revolver
NewToolLoc = Original location of the tool
OldToolMag = Magazine no. buffer storage (spindle) = 9998
OldToolLoc = Buffer storage number of the spindle
Status = 1
This action also causes the same T command to be resent to the tool-management interface if the previous T is
programmed again.
